Hybrid
Hype and a Small Price Hike |

Drive
by any car lot in the United States and
ask to see the latest hybrid car models.
Don't be stupefied if eight out of ten tell
you that they can't seem to keep them on
the lot-that they're just selling too fast!
There is reasoning behind the hype: consumers
believe in one (or all) of three things,
that they're going to be getting a better
deal once gas prices hit $2.50 a gallon,
that they're not sacrificing performance
and that they're helping the environment.
Let's first take a look at how these cars
are put together. First, we have to understand
the concept of "hybrid". A hybrid car might
be defined as any vehicle that uses two
or more sources of energy to propel itself.
Seems simple enough. Hybrid machinery is
all around us in the form of diesel-electric,
such as city buses, and nuclear-electric,
such as those used on many US submarines.
So, the idea and the technology have been
around awhile-it's just now that another
energy scare like that of the 1970s, that
we start becoming resourceful and a little
ingenious. Hybrid power is on the up-rise
(and in-demand) only because the two different
types of propulsion possibilities (gasoline/diesel
and electric) standing alone have proven
an ineffective means to get both power and
efficiency in one package. But, working
together, there is promise.
A hybrid car, in modern terminology, is
usually referring to any car that has a
combination of an electric and a gasoline
(or diesel) motors. These cars use kinetic
energy (referred to as regenerative breaking),
absorbed by your breaks when you slow down
to a stop, to recharge batteries that in
turn push the electric motor. All of this
is combined into one finely tuned schematic-the
result being power to the transmission and
propulsion power (i.e. wheel movement).
All hybrids contain a gasoline engine, an
electric engine, a generator (mostly on
series hybrids), fuel storage container,
batteries and a transmission.
There are basically two different types
of hybrid engines. The first is a parallel
hybrid. This sort of hybrid actually contains
both a gasoline and electric motor that
both operate independently to propel the
car forward. It's designed to have two power
sources working with one goal in mind. In
many ways, they are still "connected".
The second hybrid is often referred to as
a series hybrid. In a series hybrid, the
gas or diesel powered engine doesn't connect
to the transmission directly, meaning that
it doesn't actually propel the car by itself.
It actually works indirectly, powering a
generator, which in turn (controlled by
computer monitoring systems) either feeds
power to the batteries or directly feeds
power to an electric motor that connects
to the transmission.
As stated above, hybrid buyers are looking
for the combination (and compromise) of
power and energy that these cars seem to
provide. Many gas-powered cars have a lot
of horsepower. This is useful for modern
driving experiences. No one wants to be
doing the minimum 45 mph on the interstate
and stopping to "refuel," as with purely
electric motors. Plus, there's no need to
feel like you should have placed your slow-moving
reflective magnet on the trunk. However,
many gas-powered cars are truly "wasteful"
resources because out of those 175 horses,
you'll only have to use less than half that
power for everyday driving. We don't even
have to get into the harmful environmental
factors of pure gasoline engines. We are
just now starting to see the results of
our apathetic attitudes on this subject.
The engines in hybrid automobiles are usually
much smaller (except in some brand new V-6
models). While this reduces fuel consumption,
it means that for the extra "power" that
drivers are looking for has to come from
somewhere else. That's where the electric
motor and batteries come into play. In some
models, sensors detect that the car is in
need of extra energy for going up hill,
for example. That's when the "hybrid" half
of the engine kicks in. It will do a dandy
job of giving the engine that extra oomph
or boost that it needs, without using any
more gasoline.
Newer hybrid models do a lot of extra tricks
so that your car gets as many miles to the
gallon as possible. For example, when you're
stopped at a traffic light, another sensor
will trigger the gasoline engine to idle
down to a complete stop, while the car stays
"running" solely on its electric power.
Did I mention ingenious?
Since the idea behind the hybrid powered
car is reduced fuel consumption without
the loss of speed or power, many cars are
being designed to move through the streets
with the utmost in aerodynamic form; meaning
that a hybrid will create less "drag," simply
due to its body structure. Many also use
much lighter building materials, reducing
weight and pull. Some models even have wheel
covers and no mirrors (replaced with cameras
and navigation equipment), which saves an
enormous amount of energy.
Hybrids don't seem to be a fad or some social
experiment. Consumers and car enthusiasts
alike are enjoying what they're seeing in
the market. Everyday it seems a better designed,
lighter; more fuel-efficient and powerful
hybrid enters. Recently released models
are even beating their gas-powered counterparts.
One boasts a 255 hp engine with other capabilities
such as being able to shut down half the
cylinders (without notice) while in motion
to conserve fuel and energy.
Hybrid-engineered cars cost a bit more too.
Usually the price difference is around 3,000
bucks. And, it may take a few years (depending
on gas prices) for you to actually make
the savings in fuel worthwhile. However,
it's still better for the environment, and
that lingers (and makes it worthwhile) in
some consumers' minds.
And, if you are still one to wholeheartedly
grip the stick of your V-8 without budging,
you might take into mind that newer hybrid
models are gaining on those petal-to-the-metal
peelers of yesteryear. Hybrid models are
inching nearer to (and even beating!) gas
powered cars in 0 to 60 mph road tests.
So, when you decide that a new car might
be a viable option in the near future, don't
expect to see too many hybrids in dealers'
lots. You may have to do some across-the-state
driving to find a choice. Do some preliminary
searching on the Internet and find out what
model may benefit you and your lifestyle
the most. Keep in mind all that we've mentioned
and perhaps-in the future-you'll have no
other choice than a hybrid, which at this
time seems to be by far the best choice
around.
